There is a photovoltaic cell array in the front and an inverter in the back, so it is a very important product. Because the working conditions are outdoors, it has been attacked by rain and snow for a long time, and the working environment is very harsh.

Performance comparison of single polycrystalline silicon wafers
Monocrystalline silicon wafers and polycrystalline silicon wafers have significant differences in crystal quality, electrical properties, and mechanical properties. The difference between single crystal and polycrystalline is mainly in the preparation of raw materials. Single crystal is the Czochralski lifting method, polycrystalline is the ingot casting method, and there are only some minor differences in the back-end manufacturing process.
